ZBIGNIEW Assessment: Intermarium Alliance Framework

Assessment ID: ASMT-2026-003 Date: 2026-01-21 Classification: STRATEGIC Confidence: 4/5


Executive Summary

The Intermarium (Miedzymorze) concept - a geopolitical alliance spanning from the Baltic to the Black Sea and beyond - represents Poland’s most ambitious regional leadership opportunity. Originally conceived by Jozef Pilsudski post-WWI, the concept has evolved through the Three Seas Initiative (3SI) and Bucharest Nine (B9) into practical implementation. This assessment analyzes the potential for expanding these frameworks to include historical allies with demonstrated pro-Polish sentiment: Turkey, Hungary, Romania, Iran, and the Nordic-Baltic states.


1. Historical Intermarium Concept

1.1 Pilsudski’s Original Vision (1918-1939)

Scope: A federation of states between the Baltic, Black, and Adriatic Seas as counterweight to Russian and German imperialism.

Proposed Members:

  • Core: Poland, Lithuania, Latvia, Estonia, Belarus, Ukraine
  • Extended: Finland, Hungary, Romania, Czechoslovakia, Yugoslavia
  • Maximum: Scandinavia, Italy, Bulgaria, Greece (Arctic to Mediterranean)

Why It Failed:

  1. Polish distrust from Czechoslovakia and Lithuania (border disputes)
  2. Inter-regional tensions among potential members
  3. Great power opposition (Germany, Soviet Union)
  4. Lack of economic integration mechanism

What Survived: Only the Polish-Romanian Alliance (1921-1939) materialized as binding treaty.

1.2 Modern Implementations

Framework Founded Members Focus
Three Seas Initiative (3SI) 2016 13 EU states + partners Infrastructure, energy, digital
Bucharest Nine (B9) 2015 9 NATO states Security coordination
NB8 Various 8 Nordic-Baltic Security, defense
European Sky Shield (ESSI) 2022 20+ Air defense procurement

2. Countries with Historical Pro-Polish Sentiment

3.2 Cui Bono Analysis

Actor Benefit Risk
Poland Regional leadership, security depth, economic corridors Overextension, EU friction
Baltic States Strategic depth, energy access Dependency on Polish commitment
Romania NATO flank reinforcement, 3SI investment Competition for leadership
Hungary Infrastructure investment, V4 cohesion Russia policy divergence
Turkey European foothold, NATO relevance EU tensions, authoritarian concerns
Finland Baltic defense integration Drawn into Central European politics
Iran Soft bridge to Europe Sanctions complications

3.3 Who Opposes

  1. Russia - Directly threatened by encirclement
  2. Germany - Reduced Central European dominance
  3. France - Competing EU defense integration vision
  4. EU Commission - Parallel structures challenge Brussels
  5. US (partially) - Supports B9/3SI, wary of Turkey complexity

4. Pattern Recognition (ZBIGNIEW)

4.1 Historical Pattern: Failed Confederations

Every attempt at Central European confederation has failed when:

  • Imposed from outside (Habsburg, Soviet)
  • Led by dominant power seeking hegemony
  • Lacking economic integration component
  • Facing unified great power opposition

Success conditions:

  • Voluntary, consensus-based
  • Economic benefits clear and distributed
  • External threat motivation
  • Great power sponsor or neutrality

4.2 Current Opportunity Window

Favorable Factors:

  • US supports Central European cohesion (counters Russia, hedges EU)
  • Ukraine war demonstrates shared threat
  • 3SI already institutionalized
  • NATO membership provides security umbrella
  • Energy independence creates common project

Unfavorable Factors:

  • Hungary’s Russia-friendly position
  • EU-Turkey tensions
  • Iran sanctions
  • German economic leverage
  • Internal V4 disagreements

DO:

  • Build on existing institutions (3SI, B9) rather than creating new ones
  • Emphasize infrastructure/economic benefits over military bloc rhetoric
  • Cultivate historical narratives (shared memory diplomacy)
  • Engage Turkey through NATO mechanisms
  • Maintain soft cultural ties with Iran (diaspora, academic)
  • Welcome Nordic states into B9/3SI orbit

DON’T:

  • Frame as anti-EU or anti-German
  • Push Hungary into Russia’s arms with ultimatums
  • Overcommit to South Caucasus complexities
  • Expect Iran engagement beyond cultural level
  • Seek formal alliance structures that trigger opposition

5. Specific Recommendations

5.1 Immediate (1 year)

  1. Turkey: Propose bilateral defense industry cooperation (drones, ammunition)
  2. Romania: Joint Black Sea security initiative, March 3 summit
  3. Hungary: V4+ cultural diplomacy, avoid Russia ultimatums
  4. Finland: Formalize B9+ participation, defense procurement coordination
  5. Iran: Academic/cultural exchange only (Polish studies, refugee memorial)

5.2 Medium Term (5 years)

  1. 3SI Expansion: Associate membership for Turkey, Ukraine, Moldova, Georgia
  2. Nordic-Baltic-Polish Corridor: Defense industrial base integration
  3. Black Sea Strategy: Romania-Poland-Turkey coordination
  4. Energy Independence: Baltic-Black Sea pipeline/LNG network completion
  5. Historical Memory: Polish-Iranian refugee memorial in Isfahan

5.3 Long Term (20 years)

  1. Intermarium Economic Zone: Enhanced trade facilitation, infrastructure network
  2. Regional Defense Identity: NATO-compatible but autonomous capability
  3. Cultural Soft Power: Polish language/culture institutes across region
  4. Diaspora Network: Poles in allied countries as cultural bridges

6. Risk Assessment

6.1 Failure Modes

Scenario Probability Impact Mitigation
Hungary defects to Russian orbit 20% High Maintain V4 dialogue, avoid isolation
Turkey-EU break 30% Medium Engage through NATO, bilateral
US withdraws from Europe 15% Critical Accelerate European self-reliance
Germany blocks 3SI 25% Medium Emphasize EU compatibility
Internal CE disputes 40% Medium Mediation role, consensus building

6.2 Red Lines

  • No alliance structures outside NATO that could be seen as replacement
  • No engagement with Iran that violates sanctions
  • No forced choice between EU and Intermarium
  • No exclusion of Germany from infrastructure benefits

7. Validation Criteria

Prediction (5-year): If Poland successfully leads 3SI/B9 expansion:

  • 3SI membership or association will include Turkey by 2030
  • Nordic-Baltic-Polish defense coordination will be formalized
  • Romania will be Poland’s closest bilateral partner
  • Hungary will remain in structures despite Russia policy divergence

Falsification: If by 2028:

  • 3SI stagnates below 15 members/partners
  • Hungary exits V4 or B9
  • Nordic states create separate defense bloc excluding Poland
  • Turkey-Poland relations downgraded
